lviaonnnn Foie PARTITIONS AND DooRs.

` citizen of the United States, residing at the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Rollers for Partitions and Doors, of which the following is a specification, reference be- .ing had therein to the accompanying drawing. l

My invention' relates to improvements in rollers and bearings for folding, collapsible,

'or sectional walls or partitions as hereinafter more particularly set forth.

Referring to the accompanying drawings,

Figure 1 illustrates in side elevation partly broken away a portion of a folding partition illustrating an application of my invention. Fig. 2 is an enlarged cross sectional detail of the roller bearing mechanism on the line 2-2 of Fig. 1.

Each section such as 5 is preferably provided ata suitable oint at the base with a detachable roller `ear-ing, the details of which are lnore particularly set forth in Fig. 2 in which it will be observed that the base of the section is cut away as indicated at 6, said cut away portion adapted to be closed by the side plates 7-8. 9-10 are suitable Slide bearings mounted upon the slotted double screw 11 and provided with corrugations or teeth upon their lower edges adapted to'engage the pyramid bearing 1'2. 'lhis pyramid. bearing is in turn supported upon the standard 13 which terminates in the entering pin 14 and is provided with a collar or flange 15 against which is engaged the spiral spring 16, the other end of whichf bears upon the brackets 17 mounted between the plates 7--8.v Through the lower end of the standard 13 is provided' the shaft or pin 18 upon which is mounted the rollers 19 adapted to travel upon the track or plates 20-20 attached to the top of the channel Q1 in the floor 22.

From this it will be seen that the slot or crack in the runway or guide upon the floor is of minimum width and is penetrated by the foot 23 having a suitable offset such as Q-l'which prevents the door or section from jumping out of engagement with the track. 1When it is found necessary to adjust the bearing the side plates may be readily removed by taking out the screw 25 so that the necessary repairs, oiling, or other atten- .Specification of Letters Patent.
